Is the speaker a generator?
The speaker is not a generator, the speaker is a "horn". It is a very commonly used electro-acoustic transducer device, which can be seen in sound-producing electronic and electrical equipment.
Speakers can convert electrical signals into acoustic signals, and the performance of the speakers has a great impact on the sound quality. The speaker is the weakest device in audio equipment, and it is the most important component for audio effects.
There are many types of speakers, and the prices vary greatly. The audio electric energy makes the cone or diaphragm vibrate and resonate (resonate) with the surrounding air to produce sound through electromagnetic, piezoelectric or electrostatic effects.
